SPECIFICATION forming part of Letters Patent No. 655,182, dated Auguste?, 1900.

Application tied .tpiii 24, 1899.

To all whom, it may concern.-

Be it known that I, JOHN F. BECK, `a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia,

have invented a new and useful Hot-AirV Drum, of which the following is a specification.

The invention relates to improvements in hot-air drums.

One object of the present invention is to improve the construction of heating apparatus and to provide a simple and comparatively inexpensive hot-air drum designed to be arranged between twoopposite fireplaces and adapted to be heated by the lires thereof `and to supply hot air to the rooms above for heating the same. l

A further object of the invention is toprovide a heating-drum of this character which will be adapted to be employed in connection with any form of, grate or similar apparatus.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings,"and pointed out in the claim hereto appended.`

In the drawings, Figure l is a perspective view of a heating-drum constructed in accordance with this invention and shown applied to a fireplace. tional view. Fig. 3 is a longitudinal sectional 4view. Fig. 4 is a perspective view of the drum detached.

Like numerals of reference designate corre- 'spending parts in all the figures of the drawlngs.

l designates a hot-air drum designed to be arranged between two fireplaces 3 of a wall or partition 4 in position to be heated by the fires of such fireplaces to utilize the waste heat at the top and back of each fireplace for supplying hot air to the rooms above. The drum is composed of two curved upwardlydiverging sides 5, ofcast metal or other suitable material, connected at their upper edges by an arched top 6, of brick or other material, and the ends of the drum are closed by the side walls of the ireplaces. The sides 5 of the drum form the backs for the fireplaces and separate the saule, as shown in Fig. 2 of the accompanying drawings, and they present `hot air to the rooms above.

Fig. 2 is transverse sec-V Serial No. 714,211. (No model.)

increase the heating power of open grates 7 or other heating devices. The arched top G,

`which connects the upper edges of the sides of the drum, is provided with a central opening communicating with a flue 8, extending upin the' chimney 9 and adapted to conduct The lower edges of the sides of the drum rest upon the oor or base of the fireplaces, and the lower portions of such sides are substantially parallel,

and the space between them communicates with a cold-air duct 10, located beneath the rst floor and communicating with the outside air at any suitable point.

In order to cause the cold air to take a circuitous course through the drum, a series of horizontal bathe -plates or partitions l1 are employed, and they are arranged, preferably, at regular intervals and are supported by fixed flanges or ledges 12, extending from the inner faces of the sides of the drum and cast integral or otherwise mounted thereon. These horizontal plates or partitions, which extend entirely across the drum, are of less length than the same and terminate short 0f the ends thereof, being disposed in overlapping relation and forming alternate passages at the ends of the drum. The adjacent horizontal hot-air passages have their entrance and exit openings arranged at the ends of the drum, so that the cold air entering the bottom of the drum will be caused to travel back and forth from one end of the drum to the other in a serpentine course over the horizontal plates or partitions, which present a large amount of heatingsurface, so that the air before it leaves the top of the drum-will become highly heated. The longitudinal edges of the horizontal plates or partitions may be connected with the inner faces of the sides of the drum Y paratively inexpensive in construction and which is designed to be mounted betweentwo fireplaces, is heated by the superliuous heat at the back and top of such fireplaces, and it IOO i platee:-

` for the horizontai baffle-plates, whereby said heated to a high degree before it leaves the same and can be vsupplied to apartments above the apparatus by means of suitable flues and registers. The drum,whichis adapted to be used in connection with an ordinary grate, is adapted to Aincrease the effect of the tire by throwing the heat into the room, and the hot-air ilue, which extends from the top o f the drum to the apartments to be cleaned',

is located within the chimney to subject thehot air to theetect of the products of combustion passing through the chimney.

The. fireplace-heater of my invent-ion is de.- eigned 'oo be built into the fireplace the time of. building thelieeiihend 'walls oi Snidiireplnee in theY eonnse of ereoiing the ohimneyseo that one fireplace forms en integral part of fthe beaten The invention necessarily includes the cast-metal curved plates arranged in reverse positions, eo that the `limoen non tiene thereof diverge leterellmnndthe nnpei edges terminate in the same horizontal plane,

so as to form seats for the arch. The side Walle of the .fireplace close the ende of the hoi-nii eheinber formed within the platee, ee shown clearly by Fig. 3, and the arch 6 is built of brick, so as to span the space beiiween die divergent ende of the inetellie plates, the ends of said. brick areh being sented upon the opper edges of the enrved A ehereeieristio feature of n1y in7 vention ie the provision of the ledges integr-a1 with the plates and on the innieroppofsing Same horizontal piene,u thus forming Supporte v.leads from the drum, in the plates are supported removably in place, and provision ie ihne mede for theintroduction of the plates,l during the course of the installation of the ireplace-heater. arch 6 is self-supporting on the curved meiallie platee, and on thisareh is Seated the lower extremity of a single hot-air ilue, which plane of the vertical aXis thereof. e
